I have doubts:
here the temperature varies 33-35C
1) I have AA NI-MH 2600mah batteries from Toshiba, I contacted the manufacturer and he said that there is no problem with the battery life if you store 0% or 100% the reduction in battery life only occurs when recharging
2) the original Toshiba charger does not have a percentage display so I charged all AA Ni-MH 2600mah Toshiba batteries to 100% and I stored them at the temperature I mentioned, I would need to recharge them after how many days or months without harming life battery usage?
3) I have Chinese Nokia BP-5L and original Xiaomi BM20 batteries, I charged them all to 3.8v and stored them at this temperature of 33-35C, after 6 months I saw that their charge dropped a little to 3.78v, which Would it be a longer and safer period of time to charge all of them without compromising their useful life?

There are time based issues with electrolyte and plate degradation, you cannot store batteries for years.
You do have to cycle them every so often, based on your climate and storage conditions.
Wait for the experts to respond.

All battery types self-discharge faster at higher temperature. Its best not to store batteries in a discharged state (for lead-acid this wrecks them for instance).
Lithium batteries are best stored at 50% charge.
